I've got a huge huge problem. I have a notebook with a 40G harddisk. I had XP and Mandrake 10 on it, and both systems booted and ran well. Then, i installed SUsE Linux 9.0 over the Mandrake distro, and since then, Win XP does not boot anymore: the XP startup logo appears for 2 seconds and then i get a bluescreen telling me STOP 0x000000ED - UNMOUNABLE_BOOT_VOLUME.

I am totally puzzled, because i did not expect the SuSE installation routine to mess up my partition table or MBR, since all the partitions have been created before (using Mandrake). However, SuSE installed the GRUB boot manager, so maybe this has something to do with it?

I can boot Linux (which is on /dev/hda6) and it runs well, and interestingly, i can access both windows partitions from Linux (/dev/hda1 as /windows/C, /dev/hda5 as /windows/d).

To sum up: I am left now with a non-booting XP and a working linux system. However, i need XP for my job. I have read that i can run a CHKDSK from the XP recovery CD, but i am hesitating for 2 reasons: 1. i fear that this will make linux unaccessible to me (kill the grub bootmanager, etc.)2. i have to get the XP CD from the Sysadmin, who will get mad at me when i explain the situation :-]

what do you think causes my problem? how can i fix it? What would you do in my situation? Thanks!
